IMPROVEMENT N HANDLES FOR SAWS.

Specification forming part of Letters Patent No. 135,628, dated February11, 1873.

To all whom it may concern:

BE it known that I, WILLIAM OLEMsoN, of Middletown, in the county ofOrange, in the State of New York, have invented certain Improvements inHandles for Saws, of which the following is a specification:

The object of this invention is to attach an adjustable handle to ahand-saw that is used either as a cross-cut for sawing logs or wood byone man or for ripping lumber; and it consists in the construction ofthe saw-blade and the handle that is adjusted to be at different anglesupon the saw.

In the drawing, figure l is a side view of saw-blade and adjustablehandle; Fig. 2 is a side view of the saw-blade; and Fig. 3 is an edgeview of the handle.

A represents the blade of the saw, having teeth on one edge, and nearits rear end has a hole, a, in the center of the circle at the end ofthe saw and two curved slots, a a, concentric with the center hole a or,a series of holes may be used instead of the slots as seen in thedot-ted linesin Fig. 2. B is the center part of the handle, the circleof which correspondsin size to the circle on the rear end of the saw,having a center hole, a, to receive the pivotscrew b, and two othercircular holes,

a a, to receive the ho1ding-screws b I), while B B are the handles thatthe operator takes hold of to operate the saw. The center part B has atransverse slot, 0, to receive the rear end of the saw when thepivot-screw b is put into the center hole of the handle and goes throughhole a in the center of the rear end of the saw-blade and into the woodof the handle on the other side of the transverse slot and saw-blade,turning into the wood so as to hold the handle fast to the saw-blade;or, the handle may be made as seen in Fig. 2, in dotted lines. Screws 1)I) are put into the handle in the same manner as the pivot or centerscrew b, and go through the curved slots or holes a a in the saw-blade,and thence into the other part of the handle, when, by turning them uphard, they will clamp the handle and hold it firmly and at any desiredan gle on the saw-blade.

In using this saw only one man is required to operate it, and when usedas a wood-saw, commonly known as a buck-saw, or for purposes of rippinglumber, the handle may be placed as seen in Fig. 1 in dotted lines, andwhen used for cross-cutting the handles will be as seen in full lines insaid figure, or may be adjusted at any desired angle to suit theoperator.

In sawing wood as with a buck-saw, much of the weight of the ordinarysaw-frame is dispensed with hence less force is required to operate it,and a better result is obtained.

Having thus described my invention, what I claim, and desire to secureby Letters Patent,

The handle B 13, having screws b b b, in combination with the saw-bladeA having the pivot-hole a and adjusting concentric slots or-series ofholes a a, all constructed and arranged to operate in the mannerdescribed.
